The cover and casing are permanently attached to the the window trame by means of screws 9 or their equivalents.

rlhe sliding latch member G is of channel shape in cross section and comprises the bacli portion 10 having a lip i1 at its upper extremity, the flange and the llange 13 which latter llange is provided at its upper and lower ends respectively vwith the ears le and 15 arranged to be slidably protruded through the elongated slot 1G termed in the cover plate.

The ear le is provided with the downwardly and rearwardly inclined lower edge 1'? terminating in the upwardly disposed recess 1S and the ear 15 is provided with the upwardly and rearwardly inclined upper edge 19. coil spring 2O is connected at its upper end to the lip 11 upon 'the sliding latch member and at its lower end to the pin :21 upon the cover plate i' normally held ing the sliding latch member in position shown in lig. 2, the bar l upon the winconv sash being retained within. the recess 18 in the ear 14% normally holding' the window locked in the closed position.

vFor the purpose of unlocking the device from the interior i the house a wire or other Flexible member 22 is. attached through a suitable aperture 23 in the sliding atch member, this wire being connected at its upper end to a substantially horizontally disposed wire Zvi connected one end as shown at Jo to any su )le portion oi' the wall or ceiling` of the celui-f.v the other end thereotl extending some considerable distance from the wire and being connected as shown at 26 at any convenient point.

lWhen it is desired to open the window the wire 2d is grasped at a place near the connecting point 26 and a pull upon the wire will raise thD sliding latch member 6 causing the bar fl to be pushed away from the latch member as it rides upon the inclined face 19.

When the window is closed the upper edge of the bar l will engage the downwardly inclined under edge of the ear le, sliding the catch member upwardly against the. pull of the. spring until the bar passes beyond the lower end or' the edge l? when `the spring will draw the catch member down seating the bar l2 in the recess 8 locking the window.
